Description

Technical Field

[0001] This application relates to the field of nondestructive testing equipment technology, and specifically discloses a multifunctional and practical nondestructive testing vest. Background Technology

[0002] Ultrasonic testing, penetrant testing, X-ray testing, and magnetic particle testing are the four major non-destructive testing technologies, collectively known as the four conventional technologies. They are widely used in the defect detection of various materials and structures, ensuring the safety and reliability of industrial equipment, and playing a key role in manufacturing, energy, transportation, and other fields.

[0003] The principle of ultrasonic testing is that a voltage emitted by a pulse oscillator is applied to the probe (a detection element made of piezoelectric ceramic or quartz crystal). The ultrasonic pulse emitted by the probe enters the material through an acoustic coupling medium (such as machine oil or water) and propagates within it. Upon encountering a defect, some of the reflected energy returns to the probe along the original path, where it is converted back into an electrical pulse. This pulse is then amplified by the instrument and displayed on the fluorescent screen of the oscilloscope tube. Based on the position and amplitude of the defect's reflected wave on the fluorescent screen (compared to the amplitude of the reflected wave from an artificial defect in a reference test block), the location and approximate size of the defect can be determined. Ultrasonic flaw detection equipment consists of a probe, an instrument, and connecting cables.

[0004] X-ray nondestructive testing (NDT) is based on the attenuation characteristics of X-rays as they penetrate materials, utilizing the differences in X-ray absorption by different materials or defects. When high-energy X-rays penetrate an object being inspected, areas with higher density (such as metals) or defects (such as pores or inclusions) absorb more X-rays, while low-density areas (such as cracks or porosity) absorb less, resulting in an uneven distribution of transmitted X-ray intensity. This intensity variation is recorded on film (traditional RT) or a digital detector (DR / CR), forming a contrasting image that visually displays the shape, size, and location of internal defects. X-ray inspection is suitable for metals, non-metals, and composite materials, and is particularly adept at detecting volumetric defects (such as pores and shrinkage cavities) and structural anomalies. It is widely used in welding, casting, electronic components, and aerospace parts inspection. Its advantages lie in its intuitive imaging and permanent recording capability, but it has certain requirements regarding operational safety (radiation protection) and the orientation of defects (which must be aligned with the X-ray direction).

[0005] Magnetic particle testing is a method that utilizes magnetic leakage and a suitable inspection medium to detect surface and near-surface discontinuities. When magnetic lines of force pass through ferromagnetic materials and their products, a leakage magnetic field is generated at the points of magnetic discontinuity, forming magnetic poles. When dry magnetic powder is sprinkled or a magnetic suspension is poured, the magnetic poles attract the powder, producing a clearly visible magnetic trace. This trace can be used to display defects in the ferromagnetic materials and their products, revealing the location, size, shape, and severity of discontinuities under appropriate lighting. Magnetic particle testing equipment consists of a magnetic yoke, a battery, connecting wires, and a magnetic suspension.

[0006] The principle of penetrant testing is mainly capillary action. The penetrant penetrates into the surface defects, and then the surface is cleaned to remove the penetrant. The penetrant is then expelled through a developer. Sometimes a contrast agent is applied to allow for visual observation of the results. The equipment mainly consists of containers for penetrant, developer, and contrast agent.

[0007] The four conventional testing methods each have their own characteristics, and often a single device will use multiple testing methods;

[0008] Currently, ultrasonic testing requires the inspector to hold the probe in one hand and the main unit of the testing equipment in the other. When a defect is found during the testing process, it is quite inconvenient to measure the defect and it is impossible to record it. Therefore, personnel assistance is required for the operation. This is especially true in some confined spaces where one hand is needed to hold the equipment.

[0009] Magnetic particle testing requires the inspector to hold a magnetic yoke in one hand and magnetic suspension fluid in the other. One type of battery pack is a shoulder bag, where the weight of the battery is borne by the shoulder, which can easily cause shoulder pain and prevent continuous work. Another type of battery pack is a waist bag, which often loosens and slips off during inspection, walking, and climbing. In confined spaces, when a defect is found during inspection, the inspector must first squat down to place the magnetic suspension fluid container on the ground, and then stand up to measure and record the defect, which is inconvenient.

[0010] Penetrant testing currently involves carrying the penetrant in a shoulder bag, which is inconvenient for both carrying and use. Similarly, X-ray testing typically involves hanging the X-ray meter and alarm on the waist, making data viewing difficult and significantly hindering personnel movement and operation.

[0011] In many testing scenarios, multiple testing methods are required, and the work environment may necessitate working at heights or in confined spaces. This necessitates that testing personnel carry multiple testing tools simultaneously. Currently, this is typically done using a shoulder bag, which is placed at a fixed location upon arrival at the testing site. During the testing process, personnel must constantly move to the tool bag location to change tools and relocate, making the testing extremely inconvenient and inefficient. In confined space testing, air quality detectors and walkie-talkies are usually placed in the shoulder bag instead of being carried on the person, which does not meet operational requirements and hinders communication.

[0012] Currently, general work clothes do not have a dedicated design that meets all the characteristics of non-destructive testing. In view of this, this application provides a multi-functional and practical non-destructive testing vest to solve the above problems. Utility Model Content

[0013] The purpose of this utility model is to solve the problem that traditional work clothes lack a dedicated design that meets all the characteristics of the four major non-destructive testing methods.

[0014] To achieve the above objectives, this utility model provides the following basic solution:

[0015] Non-destructive testing of multi-functional and practical vests

[0016] Furthermore, the vest itself is made of an anti-static material.

[0017] Furthermore, several reflective strips are provided around the perimeter of the vest body.

[0018] Furthermore, the vest body is circumferentially fitted with a buckle loop near the wearer's waist, and the buckle loop is fitted with an adjustable waist buckle for adjusting the waist circumference of the vest body.

[0019] Furthermore, the device hanger is an X-ray meter and alarm hanger, which is used to store the X-ray meter and alarm.

[0020] Furthermore, the tool kit includes a pocket for storing a measuring tape and a steel ruler, a transparent bag for storing employee badges, and a zippered pocket for storing a notebook.

[0021] Furthermore, the vest body is vertically fixed with several buttons, one end of the ultrasonic flaw detector placement box is provided with a buckle groove that engages with the buttons, the end of the ultrasonic flaw detector placement box away from the buckle groove is provided with an ultrasonic flaw detector fixing strap, the free end of the ultrasonic flaw detector fixing strap is fixed to the shoulder position of the vest body, the ultrasonic flaw detector probe storage pocket is located on the same side of the ultrasonic flaw detector placement box, the ultrasonic flaw detector is placed inside the ultrasonic flaw detector placement box, and different types of ultrasonic flaw detector probes are placed inside the ultrasonic flaw detector probe storage pocket.

[0022] Furthermore, the number of placement pockets is at least three sets arranged horizontally, namely, a placement pocket for the penetrant tank, a placement pocket for the cleaning agent tank, and a placement pocket for the developer tank.

[0023] Furthermore, the magnetic particle detector power bank storage pocket is used to store the magnetic particle detector power bank, the magnetic particle detector yoke storage pocket is used to store the magnetic particle detector yoke, the magnetic particle detector connecting cable loop is used to fix the magnetic particle detector connecting cable, and the magnetic particle detector connecting cable is used to connect the magnetic particle detector and the magnetic particle detector power bank.

[0024] The principle and effect of this solution are as follows:

[0025] 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device is suitable for storing the four major mainstream non-destructive testing devices, freeing up hands and solving the problem that traditional work clothes lack a dedicated design that meets all the characteristics of the four major mainstream non-destructive testing devices.

[0026] 2. Compared with the existing technology, the weight of the magnetic yoke and battery in the magnetic particle detection of this device is borne by the shoulder, and the problem of the battery pack slipping off during activities is solved by placing the magnetic yoke and battery in the waist pack. In addition, a belt loop is set on the vest to prevent the belt from slipping off.

[0027] 3. Compared with existing technologies, ultrasonic testing can automatically measure defects, reducing the need for personnel assistance. It also solves the problem of limited spaces where two people cannot enter at the same time. When working at heights, one hand can be used to hold the tank wall for balance, and one hand can be used for testing. When performing magnetic particle testing, the equipment uses the shoulder to relieve force, preventing slippage. It is more beneficial for on-site testing and climbing than conventional waist packs.

[0028] 4. Compared with existing technologies, the locations used for X-ray, ultrasonic, magnetic particle, and penetrant testing do not affect each other. When performing multiple X-ray, ultrasonic, magnetic particle, and penetrant testing items, the corresponding functions can be used as needed. Attached Figure Description

[0035] Implementation, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0036] A multifunctional and practical vest for non-destructive testing includes a vest body 20. The front of the vest body 20, starting from the collar, has the following items arranged sequentially downwards: an equipment loop 1, a tool bag, an ultrasonic flaw detector storage box 15, an ultrasonic flaw detector probe storage pocket 5, a magnetic particle detector power bank storage pocket 10, a magnetic particle detector yoke storage pocket 11, a magnetic particle flaw detector connection cable loop 12, and a storage pocket 6 for penetrant testing. The ultrasonic flaw detector storage box 15 is detachably connected to the vest body 20.

[0037] Regarding the material of the vest body 20, the vest body 20 is made of anti-static material. Since the vest body 20 needs to store various instruments, it is necessary to avoid the influence of static electricity. Therefore, the entire vest body 20 is made of anti-static material to prevent static interference.

[0038] Regarding the wearing of the vest itself (20):

[0039] like Figure 2 As shown, a buckle loop 19 is circumferentially installed on the vest body 20 near the wearer's waist. The buckle loop 19 is equipped with an adjustable waist buckle 18 for adjusting the waist size of the vest body 20. The waist size can be adjusted by adjusting the adjustable waist buckle 18, so that the device fits the wearer better.

[0040] Regarding the protection of the vest body 20:

[0041] The vest body 20 has several reflective strips 17 around its perimeter, such as... Figure 1 As shown, the reflective strip 17 is arranged in a ring on the vest body 20. Since the testing environment has weak lighting, the reflective strip 17 should be provided as work clothes.

[0042] like Figure 1As shown, the equipment loop 1 is an X-ray meter and alarm loop. The X-ray meter and alarm loop is used to store the X-ray meter and alarm. When radiation detection is involved, the X-ray meter and alarm are suspended and worn on the X-ray meter and alarm loop. Radiation detection is achieved through the X-ray meter, and the alarm is a gas concentration alarm to ensure the health and safety of the staff.

[0043] The tool kit includes a measuring tape and steel ruler storage pocket 3, a transparent bag for storing name tags 4, a zippered pocket for storing notebooks 14, and a marker storage strap 13. During the ultrasonic testing process, the measuring tape, steel ruler, and other items are placed in the measuring tape and steel ruler storage pocket 3, the name tag is placed in the transparent bag for storing name tags 4, the marker is placed in the marker storage strap 13, and the notebook and other items can be placed in the notebook storage zippered pocket 14.

[0044] The ultrasonic flaw detector housing 15 is detachably connected to the vest body 20.

[0045] Specifically:

[0046] like Figure 1 As shown, the vest body 20 is provided with several buttons 16 vertically fixed. The inner end of the ultrasonic flaw detector placement box 15 is provided with a buckle groove that engages with the buttons 16. The outer end of the ultrasonic flaw detector placement box 15 away from the buckle groove is provided with an ultrasonic flaw detector fixing strap 2. The free end of the ultrasonic flaw detector fixing strap 2 is fixed to the shoulder position of the vest body 20. Since the buttons 16 are vertically fixed, when the buttons 16 are connected to the buckle groove, the ultrasonic flaw detector placement box 15 is placed horizontally.

[0047] The ultrasonic flaw detector probe storage pocket 5 is located on the same side as the ultrasonic flaw detector placement box 15. The ultrasonic flaw detector placement box 15 contains an ultrasonic flaw detector, and the ultrasonic flaw detector probe storage pocket 5 contains different types of ultrasonic flaw detector probes. The ultrasonic flaw detector is placed inside the ultrasonic flaw detector placement box 15 for use. Different models of ultrasonic flaw detector probes are placed in the ultrasonic flaw detector probe storage pocket 5 to facilitate adjustment of the probes according to changes in the object being tested.

[0048] Regarding magnetic particle testing, the system includes a magnetic particle detector power bank storage pocket 10, a magnetic particle detector yoke storage pocket 11, and a magnetic particle flaw detector connection cable loop 12. The magnetic particle detector power bank storage pocket 10 is used to store the magnetic particle detector power bank, the magnetic particle detector yoke storage pocket 11 is used to store the magnetic particle detector yoke, and the magnetic particle flaw detector connection cable loop 12 is used to fix the magnetic particle flaw detector connection cable. The magnetic particle flaw detector connection cable is used to connect the magnetic particle flaw detector and the magnetic particle detector power bank.

[0049] like Figure 1As shown, the number of placement pockets 6 is at least three sets arranged horizontally, namely, penetrant tank placement pocket 7, cleaning agent tank placement pocket 8, and developer agent tank placement pocket 9. Place the penetrant, cleaning agent, and developer in the designated placement pockets 7, 8, and 9 respectively. When performing magnetic particle, penetrant, and ultrasonic testing in a confined environment, a gas concentration alarm and a walkie-talkie can be hung on the equipment hanging loop 1, as an X-ray meter is not required on the loop 1 in this case.

[0050] When this invention is used, the locations for X-ray, ultrasonic, magnetic particle, and penetrant testing do not interfere with each other. When performing multiple X-ray, ultrasonic, magnetic particle, and penetrant testing items, the corresponding functions can be used as needed.

[0051] This device solves the problem that traditional work clothes lack a dedicated design that meets all the characteristics of the four major non-destructive testing methods.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
